COMBINED HOT-WATER HEATER AND COOKING-RANGE.

SPECIFICATIONforming part of Letters Patent No. 550,677, dated December 3, 1895. Application filed March 17, 1894. Serial No. 504,090. (No model.)

To all whom it may concern:

Be it known that we, PERRY J. EKSTRAND and LESLIE E. WATERMAN, citizens of the United States, residing at Vest Superior, in the county of Douglas and State of VVisconsin, have invented certain new and useful Imi provements in a Combined Hot-Tater I-Ieater and Cooking-Range; and we do hereby declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it ap pertains to make and use the same.

Our invention relates to an improved combined hot-water heater and cooking-range; and the invention consists in employing a hotwater heater in connection with or as a conjunction to a cooking-range, by means of which water may be kept hot for the purpose of warming houses and without interfering in any way with the operation of the range.

The objects of the invention are to provide and produce a hot-water heater in connection with a cooking-range which will be of simple construction and which can be effectively used for any desired purpose.

For a better comprehension of our invention attention is directed to the accompanying drawings, forming a part of this speciiication, in which- Figure l is afront elevation, partly in section, of our invention, showing the hot-water heater in connection with the range; Fig. 2, a longitudinal sectional view taken on the line of Fig. l, and Fig. 3 a top view of the fire-box of the hot-water heater.

In all of the above views corresponding parts are designated by the same letters of reference.

A is a cooking-range, of any approved construction, provided with a fire-box B, stack C, and flue D from the fire-box to the stack. The said range is also provided with the usual ovens, doors, and pot-holes in the top thereof. At one side of the stove A is a rectangular metallic casing E, constituting the covering for my improved hot-water heater. This casing E is preferably attached to the stove in any suitable way, such as by the angle-iron d and tie-plates b; but the said casing may be a permanent part of the stove and incapable of being removed therefrom.

F is the fire-box within the hot-water heater and is arranged some distance from the bottom thereof. This fire-box is made, preferably, of a hollow casting of the general rectangular shape shown in' Fig. `3 and with inclined inner edges c. At the bottom of the iire-box I? are the grate-bars d, of any approved construction, and vbeneath said iirebox is the ash-pit G.

II is a rectangular drum vertically mounted with the hot-water heater extending,l from the front to the baclethereof, by which means the said drum will be supported. Extending out from the said drum over the iire-box F are the pipes e, arranged in pairs and Aconnected by the double elbows f, the said pipes c being arranged as closely together as possible, so that the full effects of the heat from the fireplacer AF will be obtained. Extending out from the drum H, on the other side thereof, are the single pipes g, arranged substantially like the tubes of aporcupine boiler, each tube being provided on its end with a cap h, which may be removed and the pipes cleaned when desired.

l/Vater is admitted into the hollow fire-box F by means of a pipe t' and is circulated out of the drum H by means of a pipe j. The fire-box Fis connected to said drum by means of a pipe k. The hot water is circulated out of the drum Il and passes through any desired hot-water radiator or radiators appropriately arranged in the house and returns to the heating apparatus by the pipe e'. A short distance below the drum H, in line therewith and resting preferably on' the firebox F, is a small rectangular drum I, which extends from the front to the back of the hotwater heater. Pipes L L extend from the said drums I and convey heated water therefrom to the hot-water spigots of the house.

It will be observed that the small drum I is arranged immediately between and supports the fireplaces B and E of the range and heater, respectively, so that the water in the drum I will be heated by the fire in either of said fireplaces. The space between the drums II and I constitute a flue m, provided with a damper n therein, which can be closed when desired, and the space above the drum I-I constitutes a iiue o, through which the products IOO of combustion may pass through the ireplace F. In the top of the casing E of the hot-water heater are pot-holes p, of any suitable size and number and arranged in any desired way, for the usual purposes of cooking, &c.

The operation of our improved device will be readily understood. In summer, when it is not desired to utilize the hot-water heater, the fire is builtin the iireplace B, and the range operates in the usual way, the heat from the fire intending to heat the drum I, so that the water therein will always be kept hot for use for culinary and sanitary purposes. In winter, however, it becomes necessaryto make use of the hot-water heater, and the fire is built in the fireplace F, which is purposely larger than the fireplace B, in order that the additional heat required may be generated. The heat of the fire in the iireplace F will directly heat the hollowr firebox constituting such fireplace, and the products of combustion, passing up between and around the pipes c and against the drum H and through and around the pipes g, will heat all of these elements and the water therein. The products of combustion from the fireplace F, passing through the fiue at the top of the drum 1I and down on the other side of the drum H, will pass out through the flue d or through the range A in any suitable and desirable way. If it becomes necessary to lower the heat in the radiators, the damper n is opened and the products of combustion from the ire in the fireplace F will pass directly through the iiue m and out of the stack c. It is obvious that a damper may be placed in the iiue o; but it is not thought that this is necessary, since when the damper n is opened a large percentage of the heat will pass out through the flue m. It will also be obvious that by mounting a drum I between the fireplaces B and F the said drum will be heatedby either iire, and hot water can always be obtained therefrom for any purpose desired.

Having now described our invention, what we claim as new therein, and desire to secure by Letters Patent, is as follows:

The combination with a Cookin g range, of a hot water heater attached to or forming part of the same, comprising a hollow re box F which is mounted to one side of the fire boX of the range; a drum I mounted between said fire boxes; pipes L, L, leadingto and from said drum I, for the purpose mentioned; a drum II mounted above the drum I with a passage m between said drums; a damper 'a for said passage; circulating pipes connected with said drum H and mounted in the path of the products of combustion from the fire box F; a circulating pipe t' leading into said iire boX F; a pipe 7c connecting said fire boX F with the circulating pipes of the drum H; a

pipe j leading from said drum H; and a stack
